The object of my invention is to produce a steam-valve for steam-engines which is simpler I in construction and less liable to get out of sage, which communicates with the side of the valve, into which is introduced the hollow shaftB, which rests on bearin gs O, and through the bore 0 of this shaft the steam is exhaust ed. D-is the other hollow shaft, which rests in the bearing E. f is a hole in the hollow shaft D, which communicates with the steampassage 0 in the interior of the valve, and through which the steam is introduced into the cylinder. .F represents one side of a steamcylinder on which the valve A is placed. 9 and h are the passages into which steam is introduced and again exhausted through the action of the valve. G is a shaft, giving motion to the valve.

Having thus described my invention, I de sire to claim The steam-valve A, with passages to, b, c, and d, in combination with the hollow shafts B and D having bores e and f, bearings C and E, the steam-cylinder F, and shaft Gr, substantially as and for the purpose hereinbefore' set forth.
